Given numbers are 389, 289, 641, 964
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(389, 289) = 112421
GCD(389, 289) = ( 389 x 289 ) / 112421
= 389 / 289
= 389
Step2:
LCM(1, 641) = 641
GCD(1, 641) = ( 1 x 641 ) / 641
= 1 / 641
= 1
Step3:
LCM(1, 964) = 964
GCD(1, 964) = ( 1 x 964 ) / 964
= 1 / 964
= 1
So, Greatest Common Divisor of 389, 289, 641, 964 is 1
